Abstract

<P>PROBLEM TO BE SOLVED: To sprinkle water on a roadway surface by a water sprinkling vehicle or a person, though there are the development of a water retentive pavement material, the water permeable pavement of a roadway surface, and a countermeasure of taking heat from the periphery by the evaporation action of water by raising water detained on the roadway surface by a capillary phenomenon on the roadway surface by detaining the water on a reverse side surface of a roadway, as a heat island countermeasure against the roadway surface. <P>SOLUTION: The water sprinkled on the roadway surface uses the storage water of a rainwater underground tank, and rainwater fallen on the roadway surface is recovered by a trench curbstone, and supplied to a rainwater tank. A sprinkler head is arranged in the trench curbstone of a roadway boundary curbstone. Water the sprinkling of the storage water of the rainwater tank is automatically performed on the roadway surface by the sprinkler head by the force of a water sprinkling pump by setting a timer in the water sprinkling pump. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention is a pedestrian boundary trench that allows rainwater collected on the surface of the roadway to be collected from the surface of the roadway, and rainwater stored in the underground rainwater tank to be reused to spray the rainwater toward the surface of the roadway. Concerning the curb.

  There is Japanese Patent Application No. 2002-140791 as a conventional trench curb, but after collecting rainwater from the road surface, this trench curb allows the rainwater to be stored in the rainwater storage tank by allowing it to penetrate into the ground near the trench curb. I can't.

The above-mentioned trench curb is only rainwater collecting on the surface of the roadway, and does not have a function of sprinkling rainwater toward the surface of the roadway.
The present invention proposes a system that can collect rainwater and spray rainwater on the road surface.

In order to achieve the above object, the present invention collects rainwater falling on the surface of the roadway with the boundary trench curb of the pedestrian road, which is installed on the pedestrian road, with the trench curb, and storing the rainwater underground from the water supply pipe. Store in tank.
Water sprinkled from the trench curb is sprinkled toward the surface of the roadway from the water spigot built in the trench curb, but is sprinkled from the rainwater underground storage tank with a watering pump and sprinkled through the sprinkler pipe to the surface of the roadway.
In order to enable operation of water collection and sprinkling from the same trench curb, install two water pipes and sprinkler pipes on the trench curb, and provide a double pipe connection between the water pipe and sprinkler pipe in the rainwater underground storage tank The above problem has been solved.

  As described above, it is possible to implement flood control measures and heat island measures by providing rainwater that has fallen on the road surface to the trench curb with the same water collection and sprinkling functions.

Hereinafter, an embodiment of the present invention will be described with reference to FIGS.
FIG. 1 shows a plan view of a trench curb and tree planting zone.
The trench curb 1 has the same shape and dimensions as the conventional pedestrian border curb, the filter material 3 is placed inside the trench curb 1, and the grating lid 2 is placed on it. From the gap of the grating lid 2, The water spigot 5 is installed. The bottom of the trench curb 1 has a tunnel structure, and two pipes are installed in the tunnel structure. The water pipe 6 and the water supply pipe 7 are formed. It is connected to the watering pump 9 in the planting zone 16, and a rainwater underground storage tank 8 is installed at the tip. The water supply pipe 7 passes the water flowing down from the road surface 11 through the filter material 3. Enter the water supply pipe 7 and enter the rainwater underground storage tank 8 from the water supply pipe 7.

FIG. 2 shows a cross-sectional view of the trench curb and tree planting zone.
Water is supplied to the sprinkling pipe 6 from the rainwater underground storage tank 8 through the pumping pipe 13 into the sprinkling pump 9 in the planting zone 16, and from the gap of the grating lid 2 to the tip of the sprinkling pipe 6 by the sprinkler 5. Water 12 will appear on the road surface 11.

FIG. 3 is a plan view of the watering area on the surface of the roadway.
The range of water 12 on the roadway surface 11 is like a watering area 17.

FIG. 4 shows a cross section of the watering area on the surface of the roadway.
The road surface 11 is inclined downward from the center line 19 toward the road boundary curb, the water 12 from the sprinkler 5 returns to the return water 18 from the center line 19, and the grating of the trench curb 1 is returned. It enters the lid 2, passes through the filter material 3, enters the water supply pipe 7, and enters the rainwater underground storage tank 8 from the water supply pipe 7.
Rainwater that falls on the roadway surface 11 penetrates from the filter material 3 of the trench curb 1 and enters the water supply pipe 7 and flows into the rainwater underground storage tank 8 in the same manner as the return water 18.

Claims (1)

Rainwater that falls on the road surface at the boundary curb of the pedestrian road installed on the pedestrian road is collected by the trench curb, and the rainwater is stored in the rainwater underground storage tank through the water supply pipe.
Water sprinkled from the trench curb is sprinkled toward the surface of the roadway from the water spigot built in the trench curb, but is sprinkled from the rainwater underground storage tank with a watering pump and sprinkled through the sprinkler pipe to the surface of the roadway.
In order to enable water collection and water spraying from the same trench curb, two water pipes and sprinkler pipes were installed on the trench curb, and two water pipe and sprinkler pipe connections were installed in the rainwater underground storage tank. A system structure with water collection and sprinkling of trench curb.
